Display device

Abstract

A display device includes a display panel, a support frame including a plurality of straight portions located at two adjacent outer side surfaces of the display panel and having a substantially equal cross-section and a curved portion connecting the plurality of straight portions and having a curvature, a plurality of protrusion frames each extending from a straight portion of the plurality of straight portions of the support frame toward an inner portion of the display panel, and a mold portion overlapping the plurality of protrusion frames to be joined with the plurality of protrusion frames and being located along an inner surface of the curved portion of the support frame.

What is claimed is: 
     
       1. A display device comprising: a display panel sandwiched between an upper frame and a support frame; the support frame comprising a plurality of straight portions located at two adjacent outer side edges of the display panel and having a substantially equal cross-section and a curved portion connecting the plurality of straight portions and having a curvature; a plurality of protrusion frames each extending from a straight portion of the plurality of straight portions of the support frame toward an inner portion of the display panel opposite to the upper frame; and a plurality of support holes arranged along an extending direction of the protrusion frame is defined in the protrusion frame, each of the support holes has an opening of which a diameter continuously increases from a top surface to a bottom surface; and a mold portion overlapping the top surface of the plurality of protrusion frames to be joined with the plurality of protrusion frames and being located along an inner surface of the curved portion of the support frame, wherein at least one of the plurality of protrusion frames is not provided at the curved portion of the support frame, and wherein the protrusion frames, among the plurality of protrusion frames, extending from straight portions, among the plurality of straight portions, immediately next to each other, do not contact each other, and having a gap; the mold portion continuously covers the gap and the protrusion frames and fills the support holes. 
     
     
       2. The display device as claimed in  claim 1 , wherein the straight portion and the curved portion of the support frame have a substantially equal cross-sectional area. 
     
     
       3. The display device as claimed in  claim 2 , wherein the straight portion and the curved portion of the support frame are unitary. 
     
     
       4. The display device as claimed in  claim 3 , wherein a protrusion frame of the plurality of protrusion frames and the straight portion of the support frame are unitary. 
     
     
       5. The display device as claimed in  claim 3 , wherein the mold portion contacts an inner side of the curved portion of the support frame. 
     
     
       6. The display device as claimed in  claim 3 , wherein the support frame and the protrusion frame comprise aluminum or an aluminum alloy. 
     
     
       7. The display device as claimed in  claim 5 , wherein the mold portion comprises at least one of resins based on polyethylene, polymethacryl, polyacryl, polyolefin, polyurethane, polyester and polyamide. 
     
     
       8. The display device as claimed in  claim 5 , wherein the mold portion includes a material having lower thermal conductivity and superior ductility than those of the plurality of protrusion frames. 
     
     
       9. The display device as claimed in  claim 1 , wherein the support hole comprises at least one of a screw thread or a protruding portion therein. 
     
     
       10. The display device as claimed in  claim 3 , wherein a surface roughness of the protrusion frame is greater than a surface roughness of the support frame. 
     
     
       11. The method as claimed in  claim 5 , wherein the mold portion is continuously extends along the inner surface of the straight portion and the curved portion of the support frame.
